IMPROVEMENT IN HVDROCARBON-VAPOR BURNERS.

Specification forming part of Letters Patent No. 124,425, dated March l2, 1872.

Specification describing certain Improvements in Hydrocarbon-Vapor Lamps, invented by H. WILLIAM DoPP and MICHAEL J. STARK, both of Buffalo, county of Erie and State of New York.

The nature of our invention consists in constructing a hydrocarbon-vapor lamp so that the hydrocarbon liquid be contained in a metal bag or a diaphragm, being constructed of one or more corrugated disks or rings, from where it is to be forced, by means of uniform power, up into generating-tube; and in providing' a simple mechanism for equalizing the power aforesaid 5 for producing pressure from a sprin g; also, in constructing the burner in such a manner that the supplying and controlling of the air may be easily effected, and steady and white jet bla-zes be obtained.

The annexed drawing fully illustrates our invention. Figure l represents a Vertical section of our hydrocarbon-vapor lamp; and Fig. 2 represents a perspective view of the burner, sliding tube, and faucet, with a portion of the tube broken away to show the cam-groove.

Letter A in the drawing represents a base or stand, of either metal or other suitable material. IVithin this stand A is placed a metallic bag, B, constructed of one or more sheetmetal corrugated disks or rings, joined insuch a manner as to form a variable air-tight receptacle for the hydrocarbon liquid. It is eX- panded for the reception of the liquid by means of a stop-screw and handle, O, compound lever O1, and connecting-rod O2, and contracted for the discharge of the liquid by means of a coiled spring, O3, in combination with compound lever C1. AIt will be observed that when the stop-screw is screwed in it will strike the elbow of compound lever C1 and push it forward, thereby expanding metal bag B and also coiled spring G3. D is a faucet screwed upon stand A, and serves the purpose to facilitate adjusting the jet blazes by means of a crank-shaft and handle, D1, socket D2, and needle-rod D3. E is a tube sliding up and down upon faucet D by means of a cam-groove, E', milled within the periphery of faucet D, and a pin fastened in tube E and sliding in cam E of faucet D. F is a generating-tube screwed upon faucet D. It is provided on its upper extremity with the hydrocarbonvapor generator Gscrewed upon its outside and a plug, F', within its bore. Plug F is bored out in such a manner as to leave an opening of such a diminished size as to be scarcely perceptible. Through this opening of plug F', and closing it up entirely, extends the point of the needle of needle-rod D2. G is the hydrocarbon-vapor generator. It is provided with the igniting-cup Gl on its lower end, and also with two openings, G2 G2, for the admittance of air into the generator G, to be commingled there with the vapor arising through the orifice of plug F. H is a center tube within generator G, and is for the purpose to diminish the sound of the current of vapor in cominingling with the air, and to check the commingled gases before they reach the jet-holes G3 within the periphery of generator G. K is a regulator, consisting of an outer shell and a plug, said plug being open on one side, and having an outlet through its side and the outer shell. This outlet may be diminished by turning the plug. This regulator has the object to regulate the supply of air to be commingled with the vapor.

To operate this lamp the metallic bag B isv expanded by means of stop-screw and handle O, the faucet D taken off, and hydrocarbon liquid poured within stand A and bag B till lled; then faucet D is replaced, and tube E lowered to expose the igniting-cup; also is stop-screw C turned back to allow spring O3 to act upon bag B, and give pressure to the liquid contained therein. If, now, handle D1 is turned it will draw down socket D2 with the needle rod D3 attached to it7 and open the' orifice of plug F sufficient to allow hydrocarbon liquid to iiow out and run into igniting-cup G1. This moving of socket D2 by means of handle and shaft Dl is accomplished by the shaft being provided on its extremity with a pin placed so far out of the center of the shaft as to form a crank of sufcient throw to move the socket, in which the crank-pin turns in a corresponding bearing, as far down as necessary to withdraw the needle-point of needle-rod D3 from plug F enough to allow the liquid to. pass through orifice of plug F and run into the igniting-cup G1. If this liquid be ignited the Haine will heat the generator G sufficiently to vaporize the hydrocarbon liquid, which vapor will rise and, becoming connningled with the air entering openings G2 G2, will pass through center tube H and jetopenin gs G3 to burn in steady white blazes as soon as tube E is raised and the supply of air regulated by means of regulator K. In order to retain the iow of hydrocarbon liquid to the generator the needlerod Dsis surrounded with wicking, which, when used up, may be easily removed and replaced by a new one, as the needle-rod D3 can be easily screwed out of socket D2 (needle-bar D3 having two ears similar to those of thumb-screws) and put back again. To turn oft' the light, may be done eitherl by turning handle D2, which will force the needlerod D3 into plug F and stop the flow of vapor, or by turning stop-screw and handle C, which will expand bag B and relieve the liquid from pressure of spring C3. Be it observed that the hydrocarbon liquid is forced to the generator G by means of coiled spring` C3 attached to lever C1 and connectingrod U2; but, as this sin-ing is of g1-adually-diininishing power, and as it is required to have an equal pressure acting upon the hydrocarbon liquid, the lever C1 is, in regard to this point, so constructed that the two points where spring' C3 and connecting-rod C2 are connect-ed to it bear such rela-tion to each other th at when spring C3 is gradually losing its power its point where attached to lever G1 will always travel further from the fulcruml of lever Gl, thus increasing its leverage, while the point where connecting-rod C2 is attached to lever C1 will always travel nearer the fulcrum of lever C1, thus diminishing its leverage, and the result of this compound action will be the equalizin g 0f the power of spring U3 when acting upon the hydrocarbon liquid. Be it further observed that the peculiar construction of bag B and its device for producing pressure within the lamp does awa y with the use of atmospheric pressure and such like contrivances of a very inconvenient character for producing pressure upon the liquid within the lamp, and that, although being very silnple in its construction, it is by far superior to anything heretofore used in hydrocarbon-vapor lamps.

Claims.

H. ving thus fully described our invention, what we desire to secure by Letters Patent 1s-- l. We claim, in a hydrocarbon-vapor burner, the combination, with crank D1 and needle-rod D3, ofthe socket D27 as and for the purposes described.

2. We claim, in the construction of artificial pressure lamps, for the purpose of equalizing the power of the coiled spring C3, acting in conjunction with the metallic bag B, to force up the liquid, the combination of the coiled spring C3, compound lever G1, and bag B, constructed substantially as described.

3. We claim, in combination with coiled spring C, lever C1, and metal bag B, the stopscrew C, for the purpose set forth.

l. life claim, for the purpose of dispensing with the use of atmosphere confined in a bag and acting upon the surface ot' the liquid to be forced to the burner, 86e., in combination with a hydrocarbon aero-vapor burner, a metal bag constructed of one or more corrugated disks or rings to receive the liquid, substantially as set forth.

5. The. faucet D, provided with canrgroove E, in combination with the tube F, regulator K, and burner G, all constructed as described, and for the purposes set forth.
